If you've split a career between the United States and Denmark, the natural worry is that one pension cancels the other — that claiming in Copenhagen somehow voids what you built up in the States, or vice versa. It doesn't. You can receive a pension from each country. But the two are earned in completely different ways, and understanding that is the difference between a nasty surprise and a clear plan.
The US side: 40 credits, and the lifeline if you're short
A US Social Security retirement benefit normally requires 40 credits — about ten years of covered work. You can earn a maximum of four credits a year, so someone with nine US years has roughly 36 credits, and on their US record alone that pays nothing. It's a cliff edge.
This is where the US–Denmark totalization agreement (in force since 1 October 2008) does its job. It lets you combine your Danish coverage to reach the US qualifying threshold — provided you first have at least six US credits (about eighteen months) of your own. Clear that, and your Danish periods count toward getting you across the 40-credit line.
Two things people get wrong here. First, qualifying doesn't inflate the amount: the US benefit is still calculated on your US earnings only, then pro-rated. The Danish years open the door; they don't add to the American figure. So the realistic outcome is a partial US benefit — modest, but real, and paid alongside your Danish pension, not instead of it.
The Danish side: residence, not work
Here's the twist that trips up people who think in "years worked." Denmark's state pension — folkepension — is based on residence, not employment. It accrues on the years you were legally resident in Denmark between age 15 and retirement age, whether or not you worked in those years.
The rules in brief: you need a minimum of 3 years of Danish residence to qualify at all (and EU coordination can lower even that), and a full pension requires residence for 9/10 of the period from age 15 to retirement age — roughly 46.8 years at a retirement age of 67. Fewer years means a proportional (brøkpension) share. Crucially for an American connection, folkepension is exportable within the EU/EEA — so you can draw it even if you retire outside Denmark.
Because the Danish pension is built on residence and the US benefit on contributions, they measure different things and simply don't cancel each other. They're two separate entitlements that happen to belong to the same person.
So — both, and independently
Put together: your US benefit qualifies (often via the agreement) and pays on your American record; your Danish folkepension qualifies on residence and pays its own share. You receive both, from two systems, into whatever account you choose. Neither reduces the other.
You can sanity-check the US half in a minute with the US–Denmark totalization eligibility checker — enter your US and Danish years and it tells you whether the agreement gets you qualified.
One myth to retire: WEP is gone
For years, Americans with a foreign pension were warned about the Windfall Elimination Provision cutting their US benefit. That ended: the Social Security Fairness Act repealed WEP (and the Government Pension Offset) in 2025. If a page still says your Danish pension will shrink your US check, look at its date.
See your own numbers
The mechanics are knowable, but your actual figures depend on your specific years, earnings, and residence — and that's exactly what's tedious to work out by hand. Pensionaut does it: enter your US and Danish periods (marking which you worked and which you lived), and it returns both pensions in one consolidated estimate, with every assumption shown.
